"WOOL-WASHING MACHINE.

Application filed August 18, 1923.

To all whom if may concern.'

Be it known that I, FRED l/V. SWAIN, a citizen of the United States,residing at Dunstable, in the county of Middlesex and State oflilassachusettsl,l have invented a new and useful Vool-lVashing Machine,of which the following is a specification.

This invention relates to the ducker or immerser roll usually carried atthe feed end 'l0 of a wool washing machine.

The principal object of the invention are to provide means whereby itcan be held at different eleva-tions in the liquor and the provision ofmeans for allowing` an outlet for l5 any liquid which may work insidethe cyl1nder.

Reference is to be had to the accompanying drawings in which- Fig. l isa side view of a wool washer showing a. preferred form of my inventionapplied thereto;

F ig. 2 is a plan thereof; ant

F ig. 3 is an enlarged side view of the roll supporting means.

I have shown the invention as applied to a well known type of washingbowl 10 having a reciprocating rake 11 but I have not shown the detailsof the washing machine. The bowl is provided at the opposite sides witha pair of brackets 12 which support a pair of studs 13 in axialalignment. On each of these studs is an arm 111 pivoted to swing aboutthe stud.

One of the studs 13 is in the from of a shaft carrying a driving pulley15 and a gear 17. This gear 17 meshes with a. larger lgear 18 on a shaft19 which is supported in bearings on the two arms 14. This shaft extendsclear across the bowl and carries upon it a. rotary ducker or immerserroll 20. This is in the form of a hollow metal cylinder provided with aseries of longitudinal radially projecting blades 21 extendingthroughout the length of the cylinder. Be- 15 tween these blades thereare a series of perforations 22 through the metal walls of the cylinder.

Extending up from each side of the bowl at a convenient point are twobrackets 25 each having perforations at dierent Serial No. 658,145.

heights. Each of the arms 14 is provided with a bolt 26. These bolts aremounted movably in the arms and can be withdrawn and placed in any oneof the perforations in the bracketsI 25. In this way the cylinder can beheld at any desired elevation and immersed as far as desired in theliquor. By these bolts 26 the bearing levers la are firmly bolted inposition to hold the cylinder bearings rigidly.

In this way it will be seen that the cylinder can be placed at anydesired elevation and that any liquid which may work inside the cylindercan drain out through the perforations 22.

Although I have described and illustrated only a single form of theinvention, I am aware of thc fact that modifications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims.

Therefore I do not wish to be limited to all the details of constructionherein shown and described but what I claim is 1. The combination with awashing bowl, of a pair of pivoted bearing arms having for a sha-ft, aducker roll having a shaft resting in said bearings and extending acrossthe washing bowl, the washing bowl having supports providing withperforations at different elevations therein and bolts mounted on thebeariirg arms adapted to extend into said perforations and hold theducker roll at different elevations.

2. A combination with a u-'ashing bowl, of a pair of studs mounted onopposite sides thereof, a pair of bearing arm-s pivoted on said studsand having bearings for a shaft. a ducker roll having a shaft resting insaid bearings and extending across the washing bowl, a pair of bracketson the edges of the washing bowl having perforations at differentelevations therein and bolts mounted on the bearing arms adapted toextend into said perforations and hold the ducker roll at differentelevations.

In testimony whereof I have hereunto aflixed my signature.

FRED W. SWAIN.
